_SoaptSDR dll load error

Hello all,
I am configuring Python 3 to use pyLMS7002Soapy.
I installed both pyLMS7002Soapy and SoapySDR.
I installed Pothos with the bindig to Python.
I see the SoapSDR.dll in Pothos directory “C:\Program Files\PothosSDR\bin”
Why when I try to import either “pyLMS7002Soapy” or “SoapySDR” I have the error below?

Traceback (most recent call last):
File “”, line 1, in
File “C:\ProgramData\Anaconda3\lib\site-packages\SoapySDR.py”, line 28, in
import _SoapySDR
ImportError: DLL load failed while importing _SoapySDR: The specified module could not be found.

I am also open to suggestions about other languages to develop my own applications.
Thanks in advance
BR
Luca
